SEPARABLE COU PLING.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed October 24, 1906. Serial No. 340.339. l

To all whom, t may concern.

Be it known that I, CHARLES H. LAYNG, a citizen of the United States,and a resident of the borough of Manhattan, in the city and State of NewYork, have invented a new and useful Improvement in Separable Couplings,of which the following is a specification.

The object of my present invention is to provide certain improvements inthe construction, form, and arrangement of the several parts of aseparable coupling whereby the two members thereof may be readilyconnected and disconnected.

This separable coupling is more particularly intended for use inconnection with necklaces, but may be equally well employed in allplaces where it is desired to connect two parts by a separable coupling.

In the accompanying drawings, Figure 1 represents in side elevation thecoupling in its connected position. Fig. 2 is a longitudinal sectiontaken in the plane of the line A A of Fig. 1 looking in the direction ofthe arrows. 3 is a similar section with the two members separated, andFig. 4 is a transverse section taken in the plane of the line B B ofFig. 1.

The two members of the separable coup- A ling are of closed-endedtubular construction and are denoted by 1 and 2, and each of the membersis provided with means for the attachment of the parts to be connectedand disconnected, the means in the present instance being shown as eyes3 and 4 at the closed ends of the members.

The male member 1 of the coupling is provided on its periphery with alug 5, and the female member 2 is provided with an L- shaped recess 6 inits inner end, arranged to have a bayonet-joint connection with the lug5 of the male member. l

The means which I have shown for yieldingly holding the two members intheir connected position comprises a coil-spring 7, located in the boreof the male member 1, and a plunger 8, located centrally in the bore ofthe female member 2.

To prevent the spring 7 from escaping from within the bore of the malemember 1, I preferably make the bore of tapered form,

with its open end smaller than its closed end and make the spring ofcoils normally larger than its open end, so that when the spring isforced into the bore it will stay therein.

As the male member is inserted into the female member the plunger 8 inthe female member will engage the spring 7 and compress it, so that whenthe lug 5 has been turned laterally in its recess 6 the tension of thespring will tend to hold theA lug 5 in the end of the recess.

A separable coupling constructed and arranged as above described is verysimple and inexpensive and may be made very small in diameter, andtherefore neat in appearance, thus making the coupling particularly welladapted for use in connection with necklaces and the like.

What I claim is- 1. A separable coupling comprising tubular male andfemale members having a bayonet-joint connection, one of the membersbeing provided with a spring within its bore and the other member with alunger within its bore arranged to compress t ie spring when the membersare in their connected position, for yieldingly locking the memberstogether.

2. A separable coupling comprising tubular male and female membershaving a bayonet-joint connection, the male member being provided with aspring within its bore and the female member with a plunger within itsbore arranged to compress the spring when the members are connected andfor yieldingly locking the members together.

3. A separable coupling comprising tubular male and female membershaving a bayonet-joint connection, the male member having a tapered boreand provided with a spring held therein by the taper of the bore, and afemale member having a centrally-arranged plunger within its borearranged to compress the spring when the members are connected, foryieldingly locking the members together.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 20th day of August, 1906.
